If you think the Chinese vase at the base of the table may be valuable, you should take it (or the photos of it) to a reliable art and antiques appraiser in your area. You aren't likely to get a reliable appraisal on line.

So you want to construct the kitchen along the two 7' length walls facing each other and along the 9' wall that joins them? It can be done if the space is used practically. But first please share your floor plan to show the position of the doors and windows too. Only then can once figure out how best to utilise the space

It’s is back painted glass. As a back splash it can be used as it’s easy to clean and maintain. Highly recommended to be toughened. The entire back needs to be cladded in waterproof plywood and then the glass is stuck on to it with special adhesive or silicon gel. Any reservations on using plywood then you can opt for WPC ( wood plastic composite ) which is alternative to play and is totally termite-water proof.

Hello Priyanjali, It would be much more practical to give an advice if you could manage to provide a floor plan dimensions of the room. Regards
